Design Goals

• Our systems purpose is to be used in the field
  division of the CTU it will be dropped in a
  virus-infected zone, where it identifies any
  known viruses and remotely sends the results
  back.
• Wireless communication between the system and the
  user using Bluetooth (to prevent potential spread
  of virus)
• Can measure success by our systems ability to
  correctly identify viruses and send notification
  in a timely manner.

Architecture 1

• Description
• DSP receives input as an analog signal from PC
  using an Ethernet connection, decodes and
  converts it to a viral sequence and sends it to
  NIOS.
• NIOS receives a chunk of database and sends it to
  Flash, then runs BLASTP on it.
• NIOS sends results to ARM, then from ARM to
  Bluetooth through AVR.
• Pros
• DSP-NIOS-ARM-AVR communication already available
• Fast decoding and converting in DSP
• Cons
• Under-utilization of DSP
• Slow in producing results since input is put
  through multiple pieces of hardware

Architecture 2

• Description
• DSP receives input as an analog signal from PC
  using an Ethernet connection, decodes and
  converts it to a viral sequence and sends it to
  ARM.
• ARM searches Flash to see if input has already
  been tested.
• If results previously produced, send it to AVR.
  (cache hit)
• Otherwise, send input to NIOS.
• If a new virus, NIOS runs BLASTP and sends
  results to ARM ARM saves results in Flash, then
  sends them to AVR. (possible improvement NIOS -gt
  AVR)
• Pros
• Caching. Fast on identical inputs the more
  searches, the faster.
• Cons
• Caching fails on worst possible scenario (each
  input different from one another)

Architecture 3

• Description
• DSP receives input as an analog signal from PC
  using an Ethernet connection, decodes and
  converts it to a viral sequence and sends it to
  NIOS.
• Both NIOS and DSP communicate with PC (database)
  and each of them runs BLASTP.
• NIOS gets results from DSP, adds it to its own
  results then sends them to ARM.
  ARM-gtAVR-gtBluetooth.
• Pros
• Very fast (two BLASTPs running)
• Cons
• Complex communication/protocol

Design Exploration Plan

• Research on NIOS capabilities Ethernet
  connection, custom hardware.
• Bluetooth technology software development and
  hardware connection details.
• Research on parallel port connection to PC. (for
  Arch. 3)

11
Implementation Plan

• 2) Decision on architecture
• 3) Hello World communication
• 4) NIOS hardware implementation
• 5) DSP signal processing
• 6) Software implementation
• 7) Bluetooth integration

12
Verification and Test Plan

• Verification each unit (each piece of hardware)
  tested for correct output (correct
  functionalities).
• Integration sending simple data and echoing
  it. (Hello World)

13
Verification and Test Plan

• AVR
• Hello World on terminal
• ARM/Flash
• Simple communication between ARM and Flash
• NIOS
• Simple comparison and virus verification
• Test for correct communication with ARM
• DSP
• Simple analog signal -gt check for correct output
• Bluetooth
• Send a simple piece of data to USB Bluetooth (PC)
• Integrated System
• Check for correctness in system
• Check for consistency in results (two identical
  inputs, check for two identical results)
